I was reading Fundamentals of Inket Printing and it said the following:
"The surface tension in a liquid causes a force to act in the plane of the free surface
perpendicularly to a free edge in that surface."
Can someone explain to me what this means? What's the direction of the force? I have no idea what a free edge is. Google made me none the wiser.
